The bolt is a fastener widely used in the field of mechanical manufacturing, and consists of a nut, a screw rod and a nut, and is used for fastening and connecting two parts with through holes, the connection form is called bolt connection, if the nut is screwed off from the screw rod, the two parts can be separated, so the bolt connection belongs to detachable connection, and can be divided into a hexagonal head, a cylindrical head, a semicircular head, a sinking head and the like according to the shape of the head, wherein the hexagonal head is the most common. The outer peripheral surface of one part of the bolt head is circular, the middle of the bolt head is provided with a groove in the shape of a straight line, a cross, a hexagon and the like, the bolt head needs to be controlled to rotate by a screwdriver or an electric screwdriver matched with the groove in shape so as to be screwed or disassembled, the outer peripheral surface of the other part of the bolt head is in the shape of a hexagon, a square and the like, the bolt head does not have a groove, and the bolt head needs to be controlled to rotate by a sleeve-shaped screwdriver matched with the outer peripheral surface of the bolt head in shape. However, when the mechanical component and the electrical equipment fixed by the bolt have large areas or the space of the position where the bolt is located is narrow, the nut cannot be fixed by using a screwdriver, an electric screwdriver head, a sleeve-shaped screwdriver head or a wrench, and the bolt is only dismounted by rotating the nut, the problem that the nut, the screw rod and the nut connecting shaft rotate is often encountered, so that the nut cannot be dismounted from the screw rod, and the bolt cannot be dismounted. And current bolt dismounting device is common to solve the bolt and dismantle inefficiency, for example: CN115055956A, CN217345351U, CN114346965A, CN214722088U, or to solve the problem of high difficulty in disassembly, for example: CN216759769U, CN114888756A, CN216895289U, the prior art documents do not solve the problem of the rotation of a nut screw and a nut connecting shaft. In general, the force acting on the nut is greater than the friction force between the screw and the nut and less than the fastening force of the outside to the screw, and when the nut is dismounted, the screw cannot rotate along with the rotation of the nut to cause the situation of shaft connection; in addition, the solution of the condition that the connecting shaft rotates generally is to find another person to fix the screw and remove the nut by one person, which is the most common method, and the other method is that the working space is large enough, two components needing bolt fastening are small, one person can fix the screw by one hand and remove the nut by the other hand, but the method is only limited to the work that the bolt requires small torque.
When running into the problem that nut screw and nut even axle rotated, screw rod fixed knot constructs bigger again moreover, and a workman can not demolish fixed nut on one side, demolishs the nut on one side, and perhaps the mounted position of screw rod is narrow and small, can not hold two people simultaneously and demolish the work of bolt inside, and the bolt requires the moment of torsion great, alone can't accomplish simultaneously again at fixed screw and two during works of demolising the nut, or appear during the problem that nut screw and nut even axle rotated under other scenes, for example: the problem of connecting shaft rotation is easily caused by corrosion between the screw and the nut, the anti-loosening nut and the like, and the bolt dismounting device can finish the dismounting work of the bolt only by dismounting the nut by one person, can solve the problem of connecting shaft rotation of the screw cap, the screw and the nut, and has the following positive and beneficial effects:
1. according to the invention, the bolt dismounting device is adjusted to be in different positions, the driving gear drives the driven gear I or the driven gear II to rotate, so that different station operations are realized, when the driving gear is meshed with the driven gear I, the nut removing barrel is sleeved with the nut to drive the nut removing barrel to rotate, the device moves backwards, the nut is unscrewed for a certain distance, the dismounting of the bolt is completed, if the nut is not unscrewed, the screw and the nut are connected to rotate, the nut removing barrel is continuously driven to rotate, the device moves forwards, and the tail end of the screw is in threaded connection with the through hole of the gear shaft I; and finally, the driven gear II is driven to rotate through the driving gear, the top of the gear shaft II is unscrewed, the gear shaft II is driven to unscrew from the screw rod through the driving gear, the top of the gear shaft II is rotated, and the screw rod is rotated. According to the bolt dismounting device, the screw is matched with the first blocking shaft and the second blocking shaft, so that the rotation of the screw can be limited, the fastening force on the screw is increased, the problem that a nut screw and a nut connecting shaft rotate in the bolt dismounting process is solved, the bolt dismounting work can be completed by one person, the dismounting is rapid and convenient, the bolt dismounting device is suitable for various universal bolts, and the application range is wide.
2. According to the invention, the support ring is fixed towards one end of the nut removing barrel by the driven gear I, the nut removing barrel is fixed on the support ring, the contact area between the nut removing barrel and the support ring is large, and the nut removing barrel is fixed more firmly. The casing includes shell, protecgulum and hou gai, the mounting is fixed with the shell, the support ring passes through the bearing with the protecgulum and is connected, simple to operate, the drive shaft passes through the steel bushing with the protecgulum and is connected, drive shaft, shelves axle two pass through the steel bushing with the back lid and be connected, and the steel bushing is connected and is not only guaranteed that the casing can stable support drive shaft, shelves axle two, reduces the friction of drive shaft and two rotation processes of shelves axle, does not influence simultaneously that the drive shaft removes about, and the bearing is connected and is guaranteed that support ring and shelves axle one and nut are got rid of a section of thick bamboo and can all stably rotate and do not remove about in the casing.
3. The ejector pin is arranged at the top of the second baffle shaft, so that the friction force between the top end of the second baffle shaft and the section of the tail end of the screw rod is greatly reduced, and the second baffle shaft is easy to separate from the screw rod in the process of retreating after being tightly ejected by the screw rod. Still set up the handle of shifting in the drive shaft, the handle of shifting includes the swivel becket, with the fixed regulation pole of swivel becket, set up annular groove in the drive shaft, the swivel becket cup joints in annular groove, set up spacing hole on the shell, adjust the pole block in spacing downthehole, do not influence the position of adjusting the pole in the spacing downthehole of shell in drive shaft pivoted process, because the cooperation of annular groove and swivel becket, guarantee that the handle of shifting can not follow the drive shaft and drop moreover.
4. According to the bolt dismounting method, the driving gear on the driving shaft is adjusted to be switched between meshing with the first driven gear and the second driven gear, so that the dismounting of a conventional bolt can be solved, the nut can be loosened by tightly pushing the screw rod by the second gear shaft to enable the screw rod to rotate when the screw rod and the nut are connected with the shaft, the fastening force on the screw rod can be increased by matching the screw rod, the first gear shaft and the gear shaft, the rotation of the screw rod can be limited, and the problem of the rotation of the nut screw rod and the nut connected with the shaft in the dismounting process of the bolt is solved, and the dismounting is rapid and convenient.
